CAIRO, EGYPT—Two German men described as amateur archaeologists have been accused of entering the pyramid of Khufu without permission and stealing samples of the king’s cartouche from a compartment near his burial chamber. The two men reportedly smuggled the artifacts out of Egypt and conducted tests on them at Dresden University. The case has been referred to Egypt’s prosecutor-general and the names of the two men have been handed over to Interpol. The German embassy in Cairo has denounced the actions of the men, who were not affiliated with the German Archaeological Institute.
